ALFRED OLSON, OF SAN DIEGO, CALIFORNIA.

COVER FOR POTS OR KETTLES.

SPECIFICATION forming part of Letters Patent N 0. 661,190, datedNovember 6, 1900.

Application filed June 4, 1900. Serial No. 19,015. (No model.)

To all whom it may concern:

Be it known that I, ALFRED OLSON, a citizen of the United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented new and useful Improvements in Covers for Potsor Kettles, of which the following is a specification.

This invention relates to new and useful improvements in covers for potsand kettles; and its primary object is to provide a deviceof simple anddurable construction having means whereby the kettle, 850., upon whichit is placed may be readily ventilated to permit the escape of more orless steam, &c., as desired.

To these ends the invention consists in the novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which Figure 1 is a plan view; and Fig. 2 is asection on line 2 2, Fig. 1.

Referring to said figures by numerals of reference, 1 is the body of thecover, having an angular bead 2 formed in the upper surface thereofconcentric to its center. A bolt 3 extends upward fromthe center of thetop of the cover and is provided With a knob 4, which bears upon a slide5 of peculiar construction. This slide is provided with an ann ular bead6 upon its upper surface near one end thereof, forming a groovecorresponding and adapted to register with the bead 2 of the top of thecover, and strips 7 are struck up from the said slide at opposite sidesof the knob and clamp the lower end of the knob therebetween. Asemicircularshaped opening or slot 8 is formed in the cover, and theslide 5 is a little larger than the said slot and is adapted to entirelyclose the same when desired.

It will be seen that as the ears or projec= tions 7 firmly clamp theknob 4 said knob cannot be turned without revolving the slide therewith,said slide bearing upon the bead 2, which, together with the bolt 3,prevents lateral movement thereof. v

It will be understood that the amount of ventilation through the coverwill be regulated by the size of the opening exposed by the slide 5,and, if desired, said slide may be moved entirely from over the slot 8.

, In the foregoing description I have shown the preferred form ofmyinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall Within the scope of my invention.

Having thus described iny invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination with a cover having a slot therein; and an annular beadconcentric to the center thereof; of a slide adapted to cover the slot;a bead thereon forming a groove which corresponds and registers with thebead of the cover; a bolt engaging the slide and cover and serving as apivot for said slide; a knob secured to the bolt; and projections struckup from the slide at opposite sides of the base of the knob and clampingthe same thereto whereby said slide and knob are adapted to be turned inunison.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED OLSON.
